1 o all whom it may concern Be it known that we, DANIEL H. Teas andAUGUSTUS Vlr'ooo, citizens of the United lStates, residing,respert-ivcly, at Chicago, in the county of Cook and State of Illinois,and Hamilton, in the county of Butlerand `State of Ohio, have inventedcertain new v and useful Improvements 1n Journal Turning andBurnishing,Quartering,and Crank- Iin-Turning Machines, of which thefol'- lowiug is a specification. I

This invention relates to a machine which can be optionally used forturning or burnishing the inside or the outside journals of locomotiveor car axles, while the wheels are in place thereon; or which can beused for quartering the wheels while inv place on the axles, that is,forboring the holes in the respective wheels for the crank pins 90 apart.with either a right-hand or a lefthand lead; or which can be used forturning crank pins while in place. One object of the invention,therefore, is to provide a combined machine adapted for the usesspecified., Further objects of the invention are to .provide certainimproved features of coostruction whereby the machine can be readilytransformed or adjusted for the different kinds of work. Still furtherobjects of the invention will be apparent from the followingspecification and claims..

In the accompanying drawings we have shown the 'embodiment of. theinvention i which we now deeml preferable, but it will be. understoodthat the drawings are for illustrative purposes only and are not to -beconstrued as defining or limiting the scope of the invention, theaccompanying .claims being relied upon for that purpose.

Fig. 14 is a fragmentary plan view similar to F ig. 13, but showing themachine adjusted for turning crank pins.v

Fig. 15 is a detailed end view of the crank pin turning device. j

Figs. 1 to G show the machine adjusted for turning the inside journalsof locomotive driving or pony axles havingthe wheels in place thereon.sents the bed of the machine and 2 and 3 represent respectively thevheadstock .and tailstock which are longitudinally adjustable along thebed. nism for the headstock is,shown ats-4, and n similar adjustingmechanism for the tailstock is shown at.

A spindle 6, which is preferably non-ro tatable. is longitudinaliadjustably mounted in the headstock. his spindle carries a center 7. Asshown in Fig. 2, there is provided for adjusting the spindle a screw 8and a hand wheel 9. The tailstock 3 is As illustratedtv 1 repre,

An adjusting mecha-A spindle carrying a center 1.1. For adjustin thespindle there is rovided a screw 12 an a hand wheel 13. hen the machineis to be used for turning the inside journals of a locomotive axle, theaxle with the wheels in place thereon is mounted on the centers 7 and 11in the usual wa For rotating the wheel and ax e and for other p there isrovided a face plate 14 w ich is preferab y mounted on a non-rotatablebearm support 15 concentric with the spindle 6. he bearing sup .rt ispreferably recessed, and as shown in 1 2, a bushing 16 is .fitted in therecess to orm a supplemental support for the spindle 6. For rotating theface plate there is rovded a wer mechanism which refer-a tly comrises anelectric motor 1 carrie by a racket on the headstock. By means ofsuitable gearing 18 power is transmitted from tbe motor to alongitudinal shaft 19 at the front of the headstock. The shaft 19 isprovided at its inner or right-hand end with., a pinion 20 which mesheswith an internal gear 21 secured to the tace plate. The face plate isprovided with suitable means for turning t e wheels and axle, and forspoked wheels, this means consists of a dog 22, illustrated in Figs 1and 7, which is adapted to project between two spokes of one of thewheels. A suitable clamp may be provided for connectin the dog with oneof the spokes. The ace plate 1s provided with the usual radial T-slotsand one of these can be utilized for holding the dog 22 in place. Forwheels without spokes use may be made of the devicesshown in Fi 8 and 9and hereinafter described. Prerably `the face plate is provided with arecess 22 which is adapted to receive the crank pin of the adjacentwheel, when a .locomotive driving wheel axle is being turned. It will beseen that b means of the several parts described, the w eels and axlecan be rotated on th centers 7 and 11.

As is well known, locomotive drive wheels are ordinarily provided withcounterweights to compensate for the centrifugal action ofl the crankins and of the connecting rods when the ocomotive is in use.v Vhen thewheels and axle are detached from the locomotive and mounted on thelathe centers, they are considerably out of balance by reason of theexcess sizes of the counterweights. This lack of balance would beobjectionable in the operation of the lathe, and to compenz sate for itand restore the combined rotating parts to a balanced relation, werovide a suitable counterweight 23 which is ecured to or at leastadapted to be secured to the face plate 14.

As illustrated particularly in Fig. 7, the face plate -is provided withat least one and preferably two radial recesses 24 having parallel wallsadapted to serve as guidel in euch recess is a slide 25 which isradially 70 adjustable under the control of a screw 26.

To either of the slides 25 may be secured a counterweight 23, and byadjusting the slide the counterweight may be moved either inward oroutward, as required, to eil'ect the 75 desired balance. Preferably thecounterwei ht 23 consists of a number of sections as s own, it beingthus adjustable for locomotive wheels of different sizes. Preferably`T-slots 27 27 and 28, 28 are provided at the 80 sides of the recesses24, 24, and these slots may be used for additionally connecting theweight to the face plate. en the wheels and axle are in place, as shown,with one crank pin. rojecting into the recess 22", the 85v correspon ingcounterweight will be dia- Inetrically opposite the recess. Thecounterweight for the other wheel will be at 9()o from the first saidcounterweight and from the recess. The two counterweights on the vwheels, therefore, can be balanced by a single counterweight on the faceplate at 45 from the said recess 2 2*. As stated, the aforesaidcounterweight 23 can be secured to the face plate at either side of therecess,

thus adapting the machine for differently arran ed counterweights on thewheels,- such or instance as would be found with wheels havingright-hand or left-hand leads.

Carried by the bed of the machine is a sup ort 29 adapted to carrybrackets 30 and 31 or tool carriages 32 and 33. As shown in Fig. 5, eachbracket 30 and 31 is provided with a longitudinal guideway 34 and theguideways of the two brackets are in register, thus forming a continuousguideway along the to i. .The tool carriages 32 and 33 are adapte tomove along the combinedr guideway 34, and each carriage includes atransverse slide 35 carrying a suitable holder 110 36 for the cuttingtool or for the burnishing tool. A cutting tool is shown in Fig. 5 and aburnishing tool in'Fig. 6, and itwill be.

understood that when we herein -refer to turningwe mean to includeeither cutting or burnishing. l

For moving the carriages 32 and 33 longitudinally 'along the guidew'ay34, there is provided a longitudinal shaft 37. This shaft has a bearing38 securedl to the bracket 1.20

30 near the left-hand end thereof and a bearing 39 secured to thebracket 31 near the right-hand end thereof. The tool carriages with.Mounted on each sleeve is a vorm 42 meshlng with a worm wheel 43adaptedto be clutched to a transverse shaft 44. The

shaftl 44 carries a pinion 45 which meshes H with a rack 46 on theguidewey 34. It will thus be seen that when the shaft 3T is turned,power may be transmitted to rotate the pinion 45 and thus move thecorresponding carriage longitudinally.

Each sleeve 40 or 4i also carries e pinion 47 meshing with chiuigecuringconnecting with a longitudine shaft 49 carrying a worm 50. The worm 50meshes, with a Worm Wheel 51 on a transverse threadedA shaft 52 whichcontrols the movement of the tool slide 35. It will thus be seen thatwhen the shaft 37 is rotated the tool slide con he moved inward oroutward b means of the mechanism described in or er to foce the innernubs of the Wheels.

The shaft 37 is preferably main drive motor.y the mechanism )rovidcd forthe purpose being as follows: fear the outer left-hond end of theheedstock is a substantially vertical shaft 53 supported by a bearinbracket 54. This shaft is con nected with the shaft gearing 55. By meansof suitable worm and spur gearing 56, the shaft 54 is connected withthe` drive shaft speed mechanism 57. This mechanism has splinedengagement with :i longitudinal feed shaft 58. An inclined shaft 59 isconnected with the shaft 58 by means of bevel gearing 60, and this shaft59 is connected with the aforesaid shaft 37 by means ot' bevel gearing6i. Preferably a readily separable ioint 62 is provided between theshaft 59 and the driven element of the gearing (5G, At the driven fromthe right-hand end of the shaft 5S there is pro- Y vided other bevelearing 63 similar to the bevel gearing 60. ssociated with this bevelgearing is an element 64 simiisir to the driven element of the aforesaidjoint 62. lt will be seen that when the parts are connected, as shown,the tooi carrisges and 33 can be moved to feed the cutting tools or theburnishing tools longitudinally along the inside journals of the axle.if desired. the transverse slides 35v can be moved to feed the toolsinward or outward. The rate of feed can be adjusted by means of thechange-speed mechanism 5T.

Figs. 8 and 9 show the machine adjusted for turning or burnishing theoutside journals of locomotive trailer or ein' axles. The two centers 7and 1i are separated in :lo cordance with the, increased length oi erle.The tailstock 2 is preferably bodily moved toward the right and theheadstock is mcvvirl temporarily toward the left to permit the axle tobe put in place. The aforesaid sleeve 16 is removed from the bearingsupport i5 and the heudstock is moved so that the lefihend end of theaxle is positioned in the recess in the support, the spindle G ii'iththe center 7 being Vwithdrawn to the position shown.

For turning or buinishing outsidejournals the left-hund bracket 3U is removed from the support 29 andulaeed on the sup ort GG, :is illustrated in Pig. 8, The shaft Biffrounected with thedriven element di. being thus rotated throu h thebevel gearing G3. It! will be seen t iut the supiislementai support 66is so ioluted as to brim;r the tool carriage 32 into position to permitthe turning ot' the outside journal.

Tl "s spindleis adaptm! to curry ut its right-i nel forward end :i boring tool whicheen ne to bore o. hole of the desired diameter in the adjacent wheel, Itwill be seen that the hole can be bored at any desired distance from theaxis by raising or lowering the spindle by means of the slide and thescrewsl, 71. Preferably a su plemental bearing 78 is provided for t espindle 77, this bearing being secured to the face plate 14, asillustrated in Figs. 10 and 11. This bearing is positioned at therecess22and is held in place by means of bolts enteri T-slots 79, 79 Vinthe face plate, and it wi be clear that the bearing can be adjustedverticallyv in accordance with the vertical adjustment of the spindle.

For rotating the spindle 77 we preferably provide a separate e ectricmotor 80 carried by a bracket 81 secured to the slide 70. A train ofgearing 82 connects the motor with the spindle. the final element ofthis gear train being splined on the spindle so as to permitlongitudinal movement thereof. Suitable mechanism is provided for feedinthe spindle longitudinally. As illustrate this mechanism includes a gear83 splined on the spindle, and change-gearing 84 interposed between thegear 83 and a longitudinal feed shaft 85. The shaft 85 carries a worm 86which meshes with a worm wheel 8? on a transverse shaft 88. Thetransverse shaft 88 carries a pinion 89 which meshes with a rack 90.this rack being,r connected with the spindle so as to move itlongitudinally. It`

will be seen that whenthe spindle is rotated, power is transmittedthrough the mechanism described to move the rack longitudinally and thusInove the spindle. Preferably the Worm wheel 87 is connected with theshaft 88 by means of a clutch .controlled by a hand wheel 91. Byreleasing this clutch the shaft 88 can be turned manually by means of ahand wheel 92 toy move the spindlel lon `tudinally.

i ecured to the tailstock is a bracket 93 upon which is mounted theboring mechanism for the right-hand wheel. As illustrated by full linesin Figs. 4, 10 and 13. this mechanism is positioned at `the rear side ofthe tailstock. The bracket '93 is provided with a horizontal giiidewayon which is adjustably mounted a slide 94, this slide being adjustableby means of a screw 95. Mounted in bearings 96 and 9T on the slide 94 isa longitudinally adjustable spindle 98. The spindle is adapted to carryat its left-hand forward end a boring tool which can be set to bore ahole of the desired diameter in the adjacent wheel. It will be seen thatthe hole can be bored at any desired distance from the axis by movingthe spindle forward or backward bymeans of the slide 94 and the screw95.

For rotating the spindle 98 we preferably rovide a separate electricmotor 99 carried by the slide 94. A` train of gearing 100 connects themotor with the spindle,l the linal element of this gear train beinsplined on the spindle so as to permit longitudinal movement thereof.Suitable mechanism isl provided for feeding the spindle longitw' idinally. As illustrated, this mechanism includes a gear 101 splined onthe spindle and change-paring 102 interposed between the glearfl and alongitudinal feed'shaft 103.

he shaft 103 carries a worm 104 which meshes with a worm wheel 105 on avertical shaft 106. The vertical shaft 106 carries a pinion 107 whichmeshes with a rack 108, this rack being connected with the spindle so asto move it longitudinally. It will be seen that when the spindle isrotated, power may be transmitted through the mechanism described tomove the rack lon itudnally andthus move the spindle. Pre erably theworm wheel 105 is connected with the shaft 106 by means of a clutchcontrolled by a.

hand wheel 109. By releasing this clutch the driving mechanismstherefor, it is possible to bore crank pin holes in the two wheelssimultaneously at 90 apart.

In order that the machine may be adapted for borin crank pin holes witheither a right-han lead or a left-hand lead, we preferably make thetailstock mechanism movable so that it can be positioned either as shownby full lines in Figs. 4 and 13 or as shown by dotted lines' in the saidfigures. The bracket 93, togetherwith all of the parts carried thereby,canbe removed from the rear side of the tailstock, turned end for endand secured to the front side of the tailstock. This requires noadjustment or change of any part of the boring mechanism except theremoval of the boring tool'from one end of the spindle to the other. Theop eration of the boring mechanism in the dotted line position issubstantially the same as that already described, and repetition. of thedescription is unnecessary. The only dilference in the operation i'sthat the motor 99 is operated in the other direction in order toproperly turn the spindle 98 and to eii'ect the feed thereof in theforward direction.

' For turning crank pins in lace. use may be made of the spindle 98 anthe associated parts, these preferably being located in the positionshown by full lines in Figs. 4 and 13. 'The wheels' and axle togetherwith the crank pins may be mounted in the usual way on the centers.Frequently, however, the centers and the spindles therefor interferewith the turning. Ve therefoie provide jacks 111 which may be used tosupport the axle and wheels thus permitting the cenmental centers 111are mounted in the spindles 98 and 77 and these are engaged with thecrank pin to he turned. For turning crank pins one or more supplementaltui-xr ing mechanisms are utilized, as illustrated in Figs. 14 and 15.Each mechanism con Sists of a tool carrier 112 which is adapted to beclamped to the spindle 98 or to the spindle 77. This carrier includes alongitudinal guideway along which a tool hoh p 113 is movable. This toolholder is conu trolled by means of a screw 1M carrying a star feed wheel115. ln operation, a suitable tool is secured to the holder 113 and thespindle is rotated, Without him'crcr.V he fed longitudinally. In thisway the cai; 112 together with the tool holder 111i and he tool arebodily revolved about the crank pin. The tool is fed by means of a screwiii and the star wheel 115, the wheel engaging a suitable abutment ateach revolution. By providing two turninlar mechanisms such :is shown itis possible to turn ioth pins at 'the same time.

From the foregoing description it will be Seen that we have provided amachine which is readily capable of use for turning or burnishing eitherinside or outside journals. or for quartering, or for crank pin turning,and that the machine, notwithstandiin; 't

s several possible functions, is nevertheless comparatively simple. Thismachine is pan ticularh7 adapted for use lin small or nuL diam sized shos in which the amount ot Work is not su cient to justify the securing ofseparate machines for journal turning and burnishing, quartering, andcrank pin turning.

We do not her xin specifically claim the quartering and crank pinturningr mecha nism forming a part of the machine (lis-` closed.
